SNEEK, the Netherlands – Jumbo is using heavy-lift slings from Lankhorst Ropes to install transition pieces onto monopiles at the Yunlin wind farm offshore Taiwan.
The slings will be used to lift and position 80 transition pieces from the heavy-lift crane vessel Jumbo Javelin.
The Jumbo Javelin features two rotating mast cranes with a combined lift capacity of 1,800 metric tons (1,984 tons). For this project, 1,600 metric tons (1,764 tons) was the combined lifting capacity with the use of the Jumbo fly jib, a modular crane extension, at a maximum outreach of 28 m (92 ft).
The Lankhorst LankoForce slings are fitted to a lifting tool used to aid the correct positioning of the transition pieces weighing 450 metric tons (496 tons). As the lifting and positioning tool features multiple slings, Lankhorst has manufactured the slings to tight tolerances of + / - 1.5%.
Made from HMPE Dyneema SK78 yarns, the LankoForce endless spliced sling (grommet) are 82 mm (3.2 in.) in diameter. The transition piece lifting tool will use six endless spliced sling lengths of 6.574 m (21.57 ft) and 12 slings of 7.456 m (24.46 ft), depending on the size of the transition piece.
Located in the Taiwan Strait, some 8 km (5 mi) west of Yunlin County, the Yunlin offshore wind farm will cover an overall area of about 90 sq km (35 sq mi).
